Break

A break method is used to exit a code. A break method is used in switch statement, and also, it can be used to
exit a while, for, or do loop. For example, the break statement in the following loop terminates the loop when the end of
input is reached.

while (true)
{
   String input = JOptionPane.showInputDialog("Enter value, Cancel to quit");
   if(input == null) // leave loop in the middle
      **break**;
   double x = Double.parseDouble(input);
   data.add(x)
}

In java, there is a second form of the break statement that is used to break out of a nested statement. The statement
" break label; " immediately jumps to the end of the statment that is tagged with a label. Any statement (including if and block
statements) can be tagged with a lavel---the syntax is
label: statement
The labeled break statement was invented to break out of a set of nested loops.

outerloop:
while(outer loop condition)
{   **. . .**
   while(inner loop condition)
   {   **. . .**
      if(something really bad happened)
         break outerloop;
   }
}
//jumps here if something really bad happened//
